Abstract
This paper introduces application study of 'DREAMS'(driver's expectation and motion sensitivity) for improving 'roll feeling'.From subjective comment of test drivers who specialize in the evaluation, it is indicated that the relative movement between instrument panel and ground plays a major part in the perception of roll feeling. Then the optimal shape of instrument panel which increases driver's visual perception threshold of the vehicle roll motion by minimizing relative movement between instrument panel and ground is proposed. Further, improvement in 'roll feeling' of the vehicle with optimal shape instrument panel is examined by subjective evaluation.
